We are pleased to announce an updated version of the Northern California GeoEarthScope LiDAR in Google Earth capability that offers significantly improved browsing performance. This update features the same data as available in previous releases but achieves faster data loading in Google Earth through an updated image processing approach. In order to experience the improved performance it is necessary to download a new KMZ file. The updated Google Earth KMZ file can be downloaded from the USGS at: http://earthquake.usgs.gov/learn/kml.php or via the OpenTopography Portal at https://portal.... more

Yesterday, GEON released an updated and redesigned website (http://www.geongrid.org/). As part of the update to the GEON site, we have moved all of the LiDAR topography oriented features previously hosted in the GEON portal to a new website we are calling the OpenTopography Portal (http://opentopography.org/). The OpenTopography site provides the same core LiDAR data access and processing capabilities that were available through GEON, with streamlined access, new features, better opportunities for user discussion, and most importantly, a dedicated online space for users to find high... more

Another round of GeoEarthScope LiDAR data is now available via OpenTopography. The much anticipated Garlock fault portion of the Southern & Eastern California acquisition can now be downloaded via OpenTopography in Google Earth hillshade overlay and standard tiled DEM formats. The full data release announcement:
We are pleased to announce the availability of new GeoEarthScope airborne LiDAR data products from the Southern/Eastern California project! This release includes full coverage of the Garlock fault.

David Phillips, GeoEarthScope Project Manager, distributed an email announcement today about the Google Earth Northern California GeoEarthScope LiDAR hillshades that are available via OpenTopography:
We are pleased to announce that GeoEarthScope airborne LiDAR hillshades for the Northern California dataset can now be viewed in Google Earth. This new functionality, developed by GEON and USGS Menlo Park, makes it much easier to access and explore this rich dataset. In the words of Tom Brocher: "I think you'll be impressed with this easy new way to view the bare earth LiDAR imagery from the... more

We are pleased to announce the beta release of the OpenTopography Portal. We are still actively working to refine the user interface and navigation, and add content to the pages, but the core functionality of the system is ready and stable. For those of you that have used the GEON LiDAR Workflow running inside the GEON Portal, OpenTopography will be familiar. We hope that OpenTopography will be a more streamlined site for users to get to LiDAR data and will also offer a better environment for users to interact, discuss, and discover resources related to high-resolution topography. Please... more

GEON is responsible for the distribution of GeoEarthScope LiDAR data. We will be hosting a demo in the EarthScope booth at GSA next week to highlight access to data, Google Earth visualizations, and the OpenTopography Portal:
EarthScope Animations and Geovisualizations
Geological Society of America 2008 Annual Meeting
Houston, Texas, October 6-7
Please join us at the EarthScope booth (#130) at GSA where scientists will show their latest animations and visualizations of EarthScope data and science results on a big, 42-inch screen. The scientists will be available at the booth for informal... more

GEON, in collaboration with the USGS, has developed a Google Earth file (KMZ) that provides access to 1 meter resolution bare earth hillshades from the Northern California GeoEarthScope LiDAR topography dataset. By downloading this file and opening it in Google Earth, users are able to browse hillshades with two illumination angles (315 and 45 degrees) for faults in the northern San Andreas fault system. The Google Earth file remotely accesses data stored on GEON servers to allow users to seamlessly browse the full NoCal dataset from within Google Earth.

The entire San Andreas fault system has now been imaged utilizing GeoEarthScope Northern California Airborne LiDAR Data, along with many other important geologic features, and is available for download via the GEON Portal. This entire dataset is now available as 1 km^2 tiles of 0.5 m digital elevation models - both unfiltered (all data)and filtered (bare earth) in ESRI (ArcGIS) binary grid format. Complete metadata are also now available for download. In addition to the tiled DEM's, point cloud data are available for approximately 60% of the dataset for users who wish to download the LiDAR... more
